There was to be absolute silence during Baba's work with Nilkanthwala. No one was to pass in front of Bhau's room while Baba was inside. Kaka was told to be particularly attentive to keeping his two pet dogs, Gulu (Bhooty) and one of her pups Jolly, quiet as their loud barks disturbed Baba.
Sometimes Pukar would escort Baba to the hall after Baba's work with Nilkanthwala. "After finishing the work," Pukar recalled, "Baba always looked very tired. He would be sweating, breathing hard, sometimes shaking. Whatever work he was doing with the mast was very laborious. It was hard for Baba even to sit in his chair in the hall."
When Kumar brought Nilkanthwala to Meherazad, Nilkanthwala was keeping silence. But on 10 July 1958, while Baba was giving his "Universal Message" at the meeting in Meherabad, the mast broke his silence and began talking (sometimes nonstop!) in three languages at the same time. The mandali could understand little of what he uttered. One short sentence they were able to decipher was: "The world is a zero and in it is God!"
From 23 July, Nilkanthwala again began observing silence, using a slate and chalk to communicate — writing in English, Hindi, Bengali and Urdu. But four days later, on the 27th, he began to talk and once remarked: "The bombs will fall in the north, south and all directions. Then man-made world will finish and God-made world will revive."
Once he wrote three letters on his slate, "I. M. G." which stood for "I am going."
The mast used to cook his own food with Baidul's help. While cooking, Nilkanthwala would talk to himself. Once he uttered prophetically in Hindi: "A black cloud is gathering and people will scatter like wild beasts! The Earth will split! Men will become helpless and shelterless like beasts roaming on a plateau. Men will die in large numbers and will take birth again. Due to forced circumstances, man will be compelled to eat grass and leaves. Old human habitations will be wiped out and new ones will be established. The place of the indigenous languages like Hindi will be replaced by the English language. Rites, rituals and religious ceremonies will be eliminated."
Baba indicated that Nilkanthwala was a mast of a high caliber being on the sixth plane. Whenever Baba visited him, Nilkanthwala would take special care to offer Baba a seat, saying, "Please sit here." Once when seated before Baba, Nilkanthwala recited the Sanskrit verses that Ravana had recited in praise of Shankar (Shiva). He would sometimes praise Baba with these other Sanskrit verses: "We play with you, we speak with you, we take food with you and we make jokes with you in our ignorance [forgetting that you are Paramatma]."
In the evening of 22 July 1958, Baba repeated to the women: "The next four months will be the most difficult. You must bear it and help me. After four months, all will be well — for me, for you and for the world."
On Saturday, 2 August 1958, Baba made these remarks: "In four months, the world will know a world of difference. The jolt to the world will naturally react on me. The universe will be shaken — and the brunt of the impact will fall on me. Maya will do her best to hinder my work and will make things extremely difficult. But God will prevail and all will end well as ordained.
